Chaos synchronization between single and double wells Duffing–Van der Pol oscillators using active control

This paper presents chaos synchronization between single and double wells Duffing–Van der Pol (DVP) oscillators with Φ4 potential based on the active control technique. The technique is applied to achieve global synchronization between identical double-well DVP oscillators, identical single-well DVP oscillators and non-identical DVP oscillators, consisting of the double-well and the single-well DVP oscillators, respectively. Numerical simulations are also presented to verify the analytical results.
